Abstract
The present disclosure relates to apparatus and methods for cutting a hollow turning vane to a desired length for use in a heating, ventilation, and air conditioning (HVAC) system. The vane cutting apparatus disclosed herein utilizes a pneumatically powered cutting mechanism that allows for a smaller apparatus footprint with no loss of cutting force and results in the single stepped blade rolling the inside edges of the hollow turning vane during cutting. The rolled inside edges provide a more secure and smoother fit when the hollow turning vane is fastened to the mating vane rail for use in an HVAC duct.
Claims15
A vane cutting apparatus comprising:
- a fluid source;
- a pneumatic piston fluidly coupled to the fluid source;
- a vane cutter blade mechanically coupled to the pneumatic piston, the pneumatic piston configured to actuate the vane cutter blade between at least a proximal position and a distal position, actuation of the vane cutter blade toward the distal position configured to cut a hollow turning vane;
- a fluid control mechanism fluidly disposed between the fluid source and the pneumatic piston, the fluid control mechanism configured to control a supply of fluid from the fluid source to the pneumatic piston;
- and
- an actuation mechanism electrically coupled to the fluid control mechanism and activatable to cause the fluid control mechanism to supply fluid to the pneumatic piston, the pneumatic piston configured to actuate the vane cutter blade when the fluid control mechanism supplies the fluid to the pneumatic piston.
A vane cutting apparatus comprising:
- a blade saddle comprising a first member and a second member and configured to support a hollow turning blade when the hollow turning blade is received within the vane cutting apparatus;
- a pneumatic piston fluidly coupled to a fluid source;
- and
- a vane cutter blade mechanically coupled to the pneumatic piston, the pneumatic piston configured to actuate the vane cutter blade between at least a proximal position and a distal position, at least a portion of vane cutter blade being received between the first and second members of the blade saddle when in the distal position, actuation of the vane cutter blade toward the distal position configured to cut the hollow turning vane supported by the blade saddle.
